Purpose: To describe the Sieloff‐King Assessment of Departmental Power (SKADP) instrument and the psychometric evaluation of both the SKADP and its revision: the Sieloff‐King Assessment of Group Power within Organizations (SKAGPO) instrument. Design: A survey of 357 chief nurse executives in the United States to psychometrically evaluate the SKAGPO. Methods: Psychometric evaluation of the SKAGPO included: (a) internal consistency reliability using Cronbach's alpha coefficient, split‐half with the equal‐length Spearman Brown Correction Formula, and item analysis; (b) concurrent criterion‐related validity; and (c) factor analysis. Findings: Cronbach's alpha coefficient for the SKAGPO was.92. Subscales' alphas ranged from.63 to.88. Item‐total correlations ranged from.24 to.68, with an average item‐total correlation of.48 (n = 334). Concurrent criterion‐related validity was supported. Conclusions: The SKAGPO and the related subscales showed initial reliability and validity.
